SPECIFICATION formingpart of Letters Patent No. 526,2'11,dated September 18, 1894.

Application mea May 24, 1a 94..

To @ZZ whom it may concern:

Be it known that I, FREDERICK W. YOUNG, of Bloomfield, in the county of Essex and State of New Jersey, have invented a new and Improved `Safety-Gate, of which the following is a full, clear, and exact description:

The object of the invention is to provide a new and improved safety gate for the platforms of street cars, railroad cars, and other vehicles and places, which is comparatively simple and durable in construction, conveniently manipulated, and properly locked in either an open or a closed position.

The invention consists in certain parts and details, and combinations of the same, as will be hereinafter fully described and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the views.

Figure l is a side elevation of the improvement in a closed position and with parts in Fig. 2 is a transverse section of the same. Fig. 3 is asectional side elevation of the improvement in` an open position, and with partsin section. Fig. 4 is a transverse section of the same. Fig. 5 is a similar view of part of the improvement, on the line 5-5 of Fig. l; and Fig. 6 is an enlarged sectional plan View of part of the improvement, on the line 6--6 of Fig. 3.

The improved safety gate is provided with a casing A, preferably made U -shape in cross' section, and adapted to receive inits open end the gate proper, so as to completely conceal the" latter when in an open position. This casing or post A, is secured at its lower end on the platform B of the car on which the de-` vice is applied, the upper end of the said post being secured on the dash-board B', as plainly On the sides of the-casing A, and near the membersD D' of aset of lazy-tongs having its other set of members D2 D2, pivotally connected with the members D D', and with the pivot C on a post E, forming part of the free end of the gate, as plainly shown in the drawings. This post E is preferably made of two bars united at top and bottom, and is adapted seal no. 512,312. (No model.)

to engage keepers F held on theend B2 oi' the car, opposite the casing A, so that when the gate is in an open position, it completely closes the side of the platform, as illustrated in Fig. l.

In the upper end of the post E is arranged a vertically disposed slot E', and a similar slot E2 is arranged in the lower end of the post, the said slots receiving the transverselyextending pins G2 and G3 ofa pair of lazy` tongs G and G respectively, pivotally connected with each other at or near their iniddie, at G4, in such a manner that whenv the `gate is open, as illustrated in Fig. l, the set members of the set of lazy-tongs G G' are separate and independent of the two sets of lazy-tongs having the sets of members D D',

.D2 D2, so that the gate can be conveniently closed with all the members of the lazy-tongs foldingin the casingA within the width of the sets of bars as shown in Fig. 6. This would be impossible if the bars of both sets of lazy tongs 'were pivotally connected.

The inner ends of the lazy-tongs G G' extend through vertical slots A' A2, respectively, in the lower and upper ends of the casing A, the said lazy-tongs being pivotally connected by pivots I-I and H' respectively, with links I and I', respectively, pivotally connected with the lever J, at opposite sides of the fulcrum J of the latter arranged on the back of the casing A. The pivots I-I and H' are iitted to slide vertically in guideways A2 and A4, arranged or formed on the back of the casing A, so that when the lever J receives a swinging motion, by the operator manipulating the handle end J2 thereof, then the pivots I-I and H' are caused to slide toward or from each other, according to the direction in which the lever J is moved, thereby causing an opening and closing of the set of lazy-tongs G G', and an inward and outward sliding of the post- E to open or close the sets of lazy-tongs cornposed of the members D D', D2 D2. Thus it will be seen that the set of lazy-tongs G G are the actuating members for opening and closing the gate, it being understood that when the operator swings the handle end J2 of the lever J downward, the gate is closed,

IOO

as shown in Figs. 1 and 2, and when the said lever is swung upward the gate is opened, as illustrated in Figs. 3 and 4t.

In order to lock the lever J in either its lowermost or uppermost position, I provide bevel catches K and K secured on the inner face of the dash board B', and adapted to be engaged by the upper and lower edges of the handle end of the said lever, as will be readily understood by reference to Figs. l, 3 and 5.

The casing A is of such a Width as to accommodate all the members composing the gate proper, so that when the latter is folded, the members are completely within the said Acasing or post, so that no part of the gate proper projects when the gate-way is open. It will further be seen that the gate can be very cheaply manufactured, and easily manipulated for opening and closing the same and locking it in either of two positions.

Having thusrv described my invention, I claim as new and desire to secure by Letters Patentl. The combination of the inner and outer vertical members of the gate and a setof lazy tongs pivotally connecting said members, with a pair of crossed pivoted levers or tongs Separate and independent of said set of lazytongs and at one side thereof, the outer ends of the said crossed levers havinga sliding connection with the outer vertical member of the gate andthe inner ends being similarly connected with the said inner member, a lever bers, with a pairof cross levers or tongs separate and independent of the first set of lazy tongs and at one side thereof, the opposite ends of the said crossed levers or tongs having a sliding connection with the respective vertical members, an operating lever and links connecting the said lever with the inner slidingends of said crossed levers or tongs, substantially as described.

3. A safety gate for cars, comprising a casing formed on its back with guideways, a lever pivoted on the said casing, links pi-votally connected with the said lever at opposite sides of its fulcrum, pivotsconnected with the said links and iitted to slide in the said guideways, aset of lazy-tongs pivotally connected with the said pivots, a post having slots engaged by pins on the free ends of the said lazy-tongs, and a second set of crossed pivoted levers or tongs independent of the first set and pivotally connecting the said post with the said casing, substantially as shown and described.
